Volcanoes
We made predictions
about what would happen when we put vinegar on top of bicarbonate of
soda. Some of us got it right. We put it in a cup first and saw it
bubble, then we tried it in a bottle because it has a smaller top to see
if it would flow better. It did! We decided to make our own volcano out
of plasticine. We chose plasticine because it is waterproof. The
volcano was put into a bowl to make sure it didn't make a mess and the
bicarbonate was put in first followed by the vinegar. We were amazed at
how much the volcano erupted. The smell was terrible but we had a lot
of fun.
